A wireless access point is a Layer-2-device (like a bridge or a switch) right? Pure Layer-2 switches (without any management capabilitis, etc.) don't have MAC-addresses. They just forward Frames (Layer-2 PDUs) based on the information stored in their bridging tables.
Now when a wireless access point is a bridge between, for example, IEEE 802.3ab (Gigabit Ethernet), and IEEE 802.11n (a variation of Wireless LAN), then why does it have a Layer-2 address assigned?
I heard that the BSSID is the Layer-2 address of the wireless access point. However, if a wireless access point is a Layer-2 device, it shouldn't have a Layer-2 address, right? Just like a switch, for the pure purpose of switching, doesn't have a Layer-2 address.
So what is the BSSID actually?
